Octopoteuthis Megaptera
''Octopoteuthis'' is a genus of squid. It is one of two genera in the family Octopoteuthidae, the other being ''Taningia''. Both ''Octopoteuthis'' and ''Taningia'' are characterized by their lack of tentacles for the majority of their life cycle, and have traits characteristic of both squids and octopods. The species limits of the genus are in need of further research, for example some authorities have stated that the Mediterranean species ''Octopoteuthis sicula'' is apparently the senior synonym of ''Octopoteuthis danae'' and that it is very closely related to, or possibly conspecific with, '' Octopoteuthis megaptera''.

He explored Giza and the Pyramids with Salt. In 1818, he developed an interest in natural history, and became elected member of the ''Senckenbergische Naturforschende Gesellschaf''. He attended lectures at the University of Pavia and University of Genoa in botany and zoology. Rüppell set off on his first expedition in 1821, accompanied by surgeon Michael Hey as his assistan ...

Nomen Dubium
In binomial nomenclature, a ''nomen dubium'' (Latin for "doubtful name", plural ''nomina dubia'') is a scientific name that is of unknown or doubtful application. Zoology In case of a ''nomen dubium'' it may be impossible to determine whether a specimen belongs to that group or not. This may happen if the original type series (i. e. holotype, isotype, syntype or paratype) is lost or destroyed. The zoological and botanical codes allow for a new type specimen, or neotype, to be chosen in this case. A name may also be considered a ''nomen dubium'' if its name-bearing type is fragmentary or lacking important diagnostic features (this is often the case for species known only as fossils). To preserve stability of names, the ''International Code of Zoological Nomenclature'' allows a new type specimen, or neotype, to be chosen for a ''nomen dubium'' in this case. 75.5. Replacement of unidentifiable name-bearing type by a neotype. When an author considers that the taxonomic identity of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Guy Coburn Robson
Guy Coburn Robson (1888–1945) was a British zoologist, specializing in Mollusca, who first named and described '' Mesonychoteuthis hamiltoni'', the colossal squid. Robson studied at the marine biological station in Naples, and joined the staff of the Natural History Museum in 1911, becoming Deputy Keeper of the Zoology Department from 1931 to 1936. Evolution Robson is best known for his major book ''The Variations of Animals in Nature'' (co-authored with O. W. Richards, 1936) which argued that although the fact of evolution is well established, the mechanisms are largely hypothetical and undemonstrated.Allee, W. C. (1937)''The Variation of Animals in Nature: A Critical Summary and Judgment of Evolutionary Theories by G. C. Robson, O. W. Richards'' ''American Journal of Sociology'' 42 (4): 596–597. The book claims that most differences among animal populations and related species are non-adaptive. It was published before major developments in the modern synthesis and contains ...

Addison Emery Verrill
Addison Emery Verrill (February 9, 1839 – December 10, 1926) was an American invertebrate zoologist, museum curator and university professor. Life Verrill was born on February 9, 1839 in Greenwood, Maine, the son of George Washington Verrill and Lucy (Hillborn) Verrill. As a boy he showed an early interest in natural history, building collections of rocks and minerals, plants, shells, insects and other animals. When he moved with his family to Norway, Maine at age fourteen he attended secondary school at the Norway Liberal Institute. Verrill started college in 1859 at Harvard University and studied under Louis Agassiz. He graduated in 1862 with a B.A. He went on scientific collecting trips with Alpheus Hyatt and Nathaniel Shaler in the summer of 1860 to Trenton Point, Maine and Mount Desert Island and in the summer of 1861 to Anticosti Island and Labrador. In 1864 Verrill made reports on mining, or prospective mining, properties in New Hampshire, New York, and Pennsylvania. Tw ...

Adolf Naef
Adolf Naef (1 May 1883 – 11 May 1949) was a Swiss zoologist and palaeontologist who worked on cephalopods and systematics. Although he struggled with academic politics throughout his career and difficult conditions during World War I and II, his work had lasting influences on the fields of phylogenetics, morphology, and embryology. Life Naef was born in Herisau, Switzerland, to parents Martin and Berta. In 1904, he began studying philosophy and literature at the University of Zurich, but soon switched to natural sciences. He graduated in 1908 and went on to pursue a PhD under the guidance of Arnold Lang (1855—1914), a former Professor of Jena University and close friend of Ernst Haeckel as well as a long-time associate of Anton Dohrn.Rieppel, Olivier (2016).

Octopoteuthis Deletron
''Octopoteuthis deletron'' is a species of squid in the genus '' Octopoteuthis'' of the family Octopoteuthidae. They belong to the pelagic squids of order Oegopsida. Found at depths of in the Pacific Ocean, they have been known to grow to . ''O. deletron'' has been found to break off its arms as a defense strategy. The squid digs hooks in one of its arms into a predator and jets away, leaving the arm in the predator's skin. The male ''O. deletron'' has a penis, which is unusual among squids. Males find it difficult to detect the sex of other individuals they encounter in the dark depths, so they have adopted a strategy of attaching sperm packets to all individuals they meet. ''O. deletron'' are the most common species found in the stomachs of northern elephant seals sampled off the coast of California. It is an important prey item of the giant grenadier. It is also eaten by the enigmatic Perrin's beaked whale Perrin's beaked whale (''Mesoplodon perrini'') is part of the too ...
